Looking for 71 340 Demon broadcast sheet 1B191870

I have found them under the bottom of the rear seat, back of the rear seat, under the package shelf liner, under the carpet, on top of & behind the glove box liner, I have even heard of some finding them between the roof & headliner. Sometimes you never know where you might find it. When you DO find it, just be very careful removing it, they are usually pretty delicate after all this time.
